TCUA221WBG, TCUA2221WBG
TCUA221WBG:USB2.0 High-Speed and Audio Switch with Negative Signal Capability
TCUA2221WBG:USB2.0 High-Speed and Audio Switch with Negative Signal Capability
(With Pop Sound Eliminator at Audio Switch)
The TCUA221WBG and TCUA2221WBG are a dual SPDT
switch for combined USB2.0 High-Speed and Audio signals.
The Audio switch is designed to allow audio signals to swing
below ground.
When V
BUS
is High, the USB switchs (D+, D-) are selected,
regardless of the logic level of the Cont inputs. When V
BUS
is
Low or left open and Cont is Low, the Audio switches (R, L)
are selected.
The TCUA2221WBG also features shunt resisters on the
Audio path to reduce clicks and pop-noises.
All the inputs are protected against electrostatic discharge.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction. Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in temperature, etc.) may cause this product to
decrease in the reliability significantly even if the operating conditions (i.e. operating
temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
